Specification of Letters Piatent.

To 'ad whom it may concern:

Be 1t known that l, WILL'IAM SCHWENE, a

-'citizen of the United States, residing at gden, in the county of Bonnev and State of Iowa, haveinvented a certain newand useful Sheet-Metal Wheel, of-which the-following is a specification.

The object `of my invention is to provide an improved wheel of simple' andineXpen-- sive construction that may'beformed complete of sheet metal cut out and shaped by' ldies and that may be quickly and easily asfully set forth, pointed out in my claims and illustrated in the accompanying drawings, in whiehl l Figure 1 shows a side elevation of a complete wheel embodying my invention. l'ig. 2. shows a central, sectional lview of same. Fig. 3 shows a sectional-view on thelline 3-3 of Fig. 1, and Fig. 4 shows a sectional view on the line 1 4 of Fig. 1.

` Referring to the accompanying drawings, it will be noted thatl the spoke, felly and tire portions of the wheel are formed of .two

ieces of sheet metal. Each iece com rises a central dish-shaped 'portion 10 with thecentral opening to admit the hub portion, hereinafter described, and a number of spoke portions 11 radiating from the part 10, each being curved, as shown in Fig. 1, so that the 4edges of one spoke member will engage and rest upon the corresponding edges of the mating spoke member. At the outer ends of the spoke members is the fiat felly portion 12 through which rivets 13 are passed for connecting them together. Beyond the part 12 the felly members incline away from each other at 14C and the edges thereof are inclined straight inwardly toward each other forming the tire portions 15, the adjacent edges ofwhich touch each other as shown in Figs. 2 and 3.

ln order to firmly brace and reinforce `the inner edges of the `tire portions lo', have placed `abrouml wire or rod 16 withln the space inclosed between the felly p ortlons 14 and the tire portions 15, said wire or rod -hingthe inner; edges of the tire portions @j ffr' being rm'ly and securely held in a central. positionby the inclined walls of the felly portions v14C so that said reinforcing wire or rod does not need any other fastening device. ln this way the tread portion of the wheel is made substantially as firm and strong as though it were formedv solid of a single piece of metal. 4'

The hub portion ofthe wheel'is formed of two inner hub members and two outer hub members. Each inner hub'mernber comprises an annular flange 17, apart 418 extending from the flange 17 laterally to engage the inner edge of the part 10, a disk-shaped part 19 to lie 4flat 'against the inner face of the part 10 and a tubular bearing portion- 20 extending laterally from the projected beyond the part 10. y

The outer hub members, each comprise an annular flange 21 to lie against the outer face of the part 10 and atubular hub member 22 extended laterally andi fitting the exterior of the part'20. The outer edge .of the part 22 is turned inwardly at 23 to engage the edge of the part 20. l' connect the hub members with the part 10 by |meansof a number of rivets 24C passed through the parte 10, 19 and 21, as clearly shown in 1g. 2. Y y,

All of the parts of my improved'wheel,

part 19 and sheet metal of suitable dies.

r y. Patented Aug. 26,1913. pplication filed April'l, 1967. y Serialho. 365,885.

In assembling the' parts, l 'iirst extendthe tubular 'portions 20 of the inner hub members through the sides of the parts 10 and then place-the wire or rod 15 within the felly and tire portion and l finally place the outerV hub members in position and then insert Athe rivets. By this arrangement of parts, the hub portioninay easily be formed with a smooth inner bearing which does not need to be bored out after the wheel is assembled. These inner hub members by having their'inner portions in engagement with eachother'iirmly brace the v,hub portion of the wheel against crushing strains tending to force the parts 10 toward each other. The outer hub portions serve-' to brace and reinforce the inner ones andthey form a double thickness of metal at the point Where great, strains occur and the rivets firmly hold the hub members together and in. proper positions with relation to each' other;

The reinforcing wire 16 arranged Within these parts properly yin position against crushing stralns and 1n this Way a Wheel of vgreat strength and durability is provided that is made complete of sheet metal and` Athat is of comparativelylight Weight.

Having thus described my invention, what I claim and desire to secure by Letters wPatent of the United States, therefor isv 1. In asheet metal Wheel, the' combination of two sheet metal spokemembers and two she'et metal hub members, each of said hub members comprising an annular flange, an outwardly extended portion adjacent tothe annular flange, a disk-shaped portion toengage the inner face of the .spoke portion and a tubular bearing portion extended laterally to a point beyondl the spoke portion, the'said annular ange por immer tions of the hub members being ,r-.n engagement with each other 'and rivets passed through the spoke portions and the said disk portions.

2. In a sheet metal Wheel, the combination of sheet metal spoke portions, 'a pair of inner hub members in engagement with each other between the spoke portions andv haring tubular extensions projected laterally beyond the spoke portions, two outer hub members engaging the outer faces of the spoke portions and engagingthe tubular extensions of the inner hub members and rivets passed through the outer hub members, the spoke members and the inner hub members.
